MAYBE

'Pop* with parameter subtitution (timeout of 60.0 seconds)'
-----------------------------------------------------------
Answer:           MAYBE
Input Problem:    innermost runtime-complexity with respect to
  Rules:
    {  times(x, y) -> sum(generate(x, y))
     , generate(x, y) -> gen(x, y, 0())
     , gen(x, y, z) -> if(ge(z, x), x, y, z)
     , if(true(), x, y, z) -> nil()
     , if(false(), x, y, z) -> cons(y, gen(x, y, s(z)))
     , sum(nil()) -> 0()
     , sum(cons(0(), xs)) -> sum(xs)
     , sum(cons(s(x), xs)) -> s(sum(cons(x, xs)))
     , ge(x, 0()) -> true()
     , ge(0(), s(y)) -> false()
     , ge(s(x), s(y)) -> ge(x, y)}

Proof Output:    
  The input cannot be shown compatible
